LBA Prototype platform

The LBA platform prototype, built by Markku Postila and Toivi Iinatti. 
We are now already thinking about the LBA build next year. This will be challenging because we cannot level the field, as it will probably cause erosion and water quality problems with the nearby Siilasjärvi lake, were all the water drains to. We are now focusing on a design which involves similar raised platforms, which hopefully will allow easy position adjustments, when permafrost moves our antennas around. Another reason for the platform is that we will need to use them in order to level out the antennas, if we cannot level out the ground. In anticipation of this, Johan Borg of LTU is currently investigating the effect of such a platform on the beam pattern of an individual antenna.
